PROBLEM: The potential exists for a remotely exploitable
vulnerability in the portion of PHP code responsible for
handling file uploads, specifically multipart/form-data.
PLATFORM: HP9000 Servers running HP-UX release 11.00, 11.11, 11.20,
and 11.22 with the HP Apache product installed.
DAMAGE: Potential for increased privilege, denial of service, or
execution of arbitrary code.
SOLUTION: Download new product bundles from
http://www.software.hp.com/ISS_products_list.html
MANUAL ACTIONS: Install product bundle.
AVAILABILITY: The new product bundles are available now.
------------------------------------------------------------------
A. Background
The CERT Advisory CA-2002-21 regarding PHP, affects the
following HP products:
B9415AA Apache 1.3.x HP-UX releases 11.00 and 11.11
B9416AA Apache 2.x HP-UX releases 11.00 and 11.11
B9415AA Apache 1.3.x HP-UX releases 11.20 and 11.22
B9416AA Apache 2.x HP-UX releases 11.20 and 11.22
B9416BA Apache 2.x IPv6 HP-UX release 11.11
Before updating, make sure to stop any previous HP Apache
binary. Otherwise, the previous binary will continue running,
preventing the new one from automatically starting, although
the installation would have been successful.
The command to stop the HP Apache binary is:
for 1.3.26:
/opt/apache/bin/apachectl stop
for 2.0.39:
/opt/hpapache2/bin/apachectl stop
HP Apache automatically starts upon installation if port 80
is available.
Installation of this new version of HP Apache over an existing
HP Apache installation is supported, while installation over a
non-HP Apache is NOT supported.
==================================================================
Case id: SSRT2300 - HP Tru64 UNIX, HP OpenVMS, and Internet
Express V5.9
o Secure Web Server for HP OpenVMS and HP Tru64 UNIX are not
vulnerable.
o Internet Express V5.9 contains PHP 4.1.2 which is not
listed as vulnerable to this problem. We also have provided
an externally downloadable Secure Web Server 5.9.1 kit (with
security fixes to Apache) that also contains PHP 4.1.2.
B. Fixing the problem
Note: OpenView Network Node Manager (NNM) customers should not
install these bundles. The version of Apache delivered
with NNM is under investigation. This bulletin will be
updated when more information is available.

bundles rather than patches.
